UWP1C4R7MCL1GB

The UWP1C4R7MCL1GB is a chip-type aluminum electrolytic capacitor from the Nichicon UWP series, specified as a bi-polar surface-mount device. It delivers 4.7 µF capacitance at a 16 V rated voltage in a compact SMD can package optimized for automatic placement on high-density printed circuit boards.

Engineered for reliability in demanding environments, the part is AEC-Q200 qualified, RoHS compliant, and specified for operation from −40 °C to +85 °C with a rated life of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage: 4.7 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance (120 Hz, 20 °C).
• Bi-Polar Construction: Bi-polar polarization suitable for applications where polarity inversion may occur; endurance testing includes polarity inversion every 250 hours during the 1000 h at 85 °C test.
• Compact SMD Can Package: Radial, can-style SMD with body dimensions L: 5.4 × D: 4 mm and recommended land size L: 4.3 × W: 4.3 mm for high-density board layouts.
• Automated Assembly Compatible: Designed for surface mounting on high-density PC boards and applicable to automatic mounting machines fed with carrier tape.
• Thermal & Endurance: Rated for −40 °C to +85 °C operation with a specified lifetime of 1000 hours at 85 °C; meets endurance limits for capacitance change, tan δ, and leakage current after test.
• Ripple Current Data: Low-frequency ripple current of 12 mA at 120 Hz and high-frequency ripple current of 18 mA at 10 kHz to support ripple filtering applications within specified limits.
• Manufacturing Robustness: Resistance to soldering heat validated by 30 s exposure on a 250 °C hot plate with characteristic retention within specified limits.
• Compliance & Qualification: RoHS compliant and AEC-Q200 qualified as noted in the product data.

Typical Applications

• Automotive Electronics: Suitable for use in automotive modules where AEC-Q200 qualification and operation across −40 °C to +85 °C are required.
• Power-Rail Decoupling: Used for smoothing and ripple filtering on DC power rails, leveraging specified ripple current ratings at 120 Hz and 10 kHz.
• AC-Coupling / Signal Conditioning: Bi-polar construction supports circuit topologies where polarity may invert, such as certain coupling or filtering stages.
• High-Density PCB Designs: Compact chip can package and SMD land pattern enable placement in space-constrained board designs and automated assembly workflows.

Unique Advantages

• AEC-Q200 Qualification: Provides documented suitability for automotive and similarly demanding system designs that reference AEC-Q200 requirements.
• Bi-Polar Flexibility: Bi-polar polarization and endurance testing with polarity inversion reduce restrictions in circuit placement where polarity may reverse.
• Automated Assembly Ready: Carrier-tape compatibility and SMD can format simplify integration into high-volume automated production lines.
• Compact Footprint: Small L × D dimensions (5.4 × 4 mm) and a tight recommended land pattern help save board area in dense designs.
• Specified Endurance and Thermal Range: 1000 h at 85 °C life rating and −40 °C to +85 °C operating range provide predictable aging and performance for duty-cycle planning.
• RoHS Compliance: Meets RoHS directive requirements for use in lead-free and restricted-substance product builds.
